How to plan B2B demand generation webinars: timing, consent and follow-up

What to take away

Why the channel suits UK business buyers

A webinar packs a sales conversation into 45 minutes and gives a buying group a shared reference point. Where a deal involves finance, operations and a technical lead, that shared context shortens the internal debate.

The format also fits modest budgets. You need a topic, a host who knows the subject and a registration page. Platform fees vary, so the real cost sits in promotion and follow-up.

A live online seminar with polls, a chat panel and a recording sits inside the wider category Wikipedia calls web conferencing.

If your target list is small and named, a session built around shared problems beats a broad topic. Account-based marketing for business-to-business demand generation covers how to choose those accounts before you write the invite.

Choosing a slot that works across the UK

The UK runs on one clock, so you are not balancing zones inside Great Britain and Northern Ireland. British Summer Time still catches people out: 14:00 in July is 13:00 UTC, which overseas colleagues often misread.

Practical slots sit between 10:00 and 14:00 on Tuesday, Wednesday or Thursday. Friday afternoons and school holiday weeks drain attendance. A 15:00 UK start catches the US East Coast morning without asking anyone to log on before 07:00.

Name the zone in the invite as BST or GMT rather than UK time, and repeat it in the reminder email.

Consent, registration and personal data

Registration collects personal data, so UK GDPR applies from the first field. The ICO guide to the UK GDPR sets out the lawful bases and the transparency you owe registrants, including what you tell them about sharing data with partners.

Consent is not the only lawful route, but for marketing email it is the cleanest. Use a separate, unticked box that names your organisation and describes what will arrive. The ICO guidance on direct marketing and electronic communications explains when consent is required for email and when the soft opt-in can apply.

Pre-ticked boxes and bundled terms do not meet the standard for consent, so keep the wording plain and specific.

Store the consent record with a timestamp, the wording shown and the page it came from, so you can answer a subject access request later.

Follow-up that keeps the pipeline warm

Scoring works better on behaviour than on a single attendance flag. A 40-minute stay with two poll answers signals more interest than a sign-in and a quick exit.

Layer that behaviour onto third-party buying signals and you get a sharper order of priority; our guide to using intent data for business-to-business demand generation explains how to combine them without over-contacting buyers.

Common questions

How long should a business-to-business webinar be?

Forty-five minutes of content plus 15 minutes of questions suits most UK audiences. Anything past 90 minutes loses the room, so split the material across two sessions instead.

Do I need consent to email webinar registrants?

For marketing email, yes, unless an exception applies. Registering does not by itself create a marketing permission, so collect a separate opt-in at sign-up.

Should we run the webinar on LinkedIn or our own platform?

Either can work. An owned platform gives you the full registration list and clean consent records, while a social platform may bring a larger cold audience. Check who owns the attendee data before you commit.

How do we measure demand rather than registrations?

Track attendance rate, questions asked, replay views and meetings booked from the session. Registration numbers on their own say little about whether buyers moved.
